Your Profile
We’re looking for someone who is deeply proactive and accountable - someone who doesn’t just identify problems but owns them, and is energized by bringing clarity and progress to complexity.
Mandatory Requirements
3+ years of experience in business development, project origination, key account management, or energy markets
Strong knowledge of the Polish energy landscape, ideally including renewables, grid-scale storage, or power trading
Excellent communication and negotiation skills in Polish and English
Experience building strong, trust-based relationships with senior stakeholders and project developers
A proactive, self-starting mindset — you don’t wait for permission to create impact
Full ownership of your projects — you see obstacles as opportunities to act, not as reasons to stall
High adaptability and comfort with change — you embrace learning and iteration in a dynamic
Skills to Set You Apart
You bring a proven track record in originating BESS projects and closing commercial agreements with developers or investors
You have a strong sense of agency: you’re someone who turns ideas into action and doesn’t just talk about change - you lead it
You operate with a growth mindset: you see challenges as opportunities, adapt fast, and are constantly learning
You are deeply responsible: when you see a problem, you take ownership and drive toward solutions, rather than waiting to be asked
You enjoy working in an early-stage, entrepreneurial environment where building processes, relationships, and value go hand in hand
This role may not be a fit for you if…
You prefer roles with limited customer and cross-team interactions
You are not comfortable working in a fast-paced, evolving regulatory and technical landscape
You are not familiar with the Polish energy landscape and not interested in actively building expertise in the battery storage space
We are committed to diversity - of all backgrounds and experiences. You don’t need 100% of the preferred qualifications to add incredible value to our team. If you’re passionate about what you could accomplish here, we’d love to hear from you.
A Short Note from Your Future Lead
"Hi there,
I’m Aleksandra, and I’m Country Manager Poland at Entrix. Over the past years, I’ve worked with some of the largest renewable energy investors across Europe. I’ve negotiated PPAs, built commercial partnerships, developed new services like battery optimization, and managed a portfolio of over 1.7 GW. I’ve worked on both strategy and execution, and I’ve seen first-hand how fast this market is evolving.
At Entrix, we’re building something ambitious — a smart, tech-driven platform to unlock the full value of battery storage in energy markets. In Poland, this means we’re often first movers. We work at the intersection of energy markets, technology and regulation. The projects are complex, the landscape is evolving quickly, and our customers rely on us to help them make their battery projects bankable and successful.
To succeed here, three things matter most: agency, adaptability, and accountability. We need people who take ownership, drive things forward without waiting to be asked, and are ready to adjust course as the market shifts.
If you’re someone who enjoys turning ideas into action, solving real-world problems, and working closely with a tight-knit and ambitious team, I believe you’ll enjoy being part of what we’re doing here.
Looking forward to what we’ll create together,
Aleksandra"
About us
With our AI-powered fully automated optimization and trading platform for flexible energy assets from grid-scale batteries to virtual power plants, we ensure that energy is stored when it is abundant and released into the grid when it is needed. At the same time, by actively trading electricity, we counteract strong price fluctuations that green energies entail. Figuring out how storage provides the best value to the electricity grid and the highest returns to asset owners is how we accelerate the transition to a clean energy future.
